Should I remove bathtub mold myself or call a professional?« Back to Previous Page

That black mold under the silicone is a common issue in Dubai due to our high humidity and the condensation that builds up in bathrooms from constant AC use. The symptoms you describe—headaches, stuffy nose, and a persistent musty smell—are typical reactions to mold exposure.

For a small, visible patch (under one square foot), you can attempt to clean it yourself. The key is addressing the source, not just the surface. You must remove and replace all the compromised silicone sealant, as the mold grows through it. After removal, scrub the area beneath with a solution of detergent and water, then disinfect with a product like white vinegar or a diluted bleach solution. Ensure the area is completely dry before applying new, high-quality mold-resistant sealant.

However, given that the mold was hidden and you're experiencing physical symptoms, a professional assessment is strongly recommended. The mold you see is often just the surface of a larger colony that can penetrate porous grout or wallboard behind the tiles. Disturbing it incorrectly can aerosolize spores and worsen your indoor air quality.

In the UAE, reputable remediation companies follow standards like the IICRC S520. They will conduct an inspection, often using moisture meters and borescopes, to determine the full extent of the problem. The safest approach is to have them contain the area, remove the contaminated materials safely, and address the underlying moisture source—which could be a small leak or simply inadequate ventilation. For health-related concerns, this is the most effective path to ensure the problem is resolved completely.
